Is it just me, or is Hasbro taking a huge chance by only releasing the "Hero" of the game in a 20.00 + set? Wouldn't it have made sense to have these carded, so kids could actually choose the one they wanted? Not ony that, but with Hasbro's poor scheduling, I bet that this set, and the carded figures hit at very different times.
I think that an Evolutions set was the only way they could give us all three in-game versions of the Apprentice.
If they had individually carded the Apprentice character there was no way that they could have put all three versions into the assortment.
The big problem here is that the Force Unleashed project was postponned from 2007. If it had come out as planned then sure, perhaps carding the Apprentice would have been okay, but with The Clone Wars cartoon and toy-line on the horizon. Hasbro has a very small window with which to strike with Force Unleashed merchandise. If we didn't get the Jedi Knight version of the apprentice now, there's a chance we'd never get him.
Also, think about it - there's no way that the Sith Lord outcome will be the canon ending that is presented in the comics and the book. Clearly the Sith Lord outcome is as a result of either killing Vader or helping Vader kill the Emperor or even possibly killing them both - and since the game pre-dates ANH, we all know that doesn't happen.
What IS more likely is that the love between Juno and the Apprentice pushes him to the light-side, he squares off against Vader and is put into a situation where he ends up dead or in hiding. In fact almost as a tongue-in-cheek type result, I could see them working something into the game where Vader is almost like "damn, I wish I hadn't killed Padme, she could have birthed a son who could have been my apprentice and surely my son wouldn't have turned on me! blah blah blah..."
